Receiver Commands - ashtech GG Surveyor Reference Manual

Receiver Commands

Receiver commands change or display various receiver operating parameters such as
recording interval, antenna position, and PDOP mask. Commands may be sent
through any available serial port.
Set Commands
The general structure of the set commands is:
where str is a 3 character string identifier, and x is one or more data parameters that
will be sent to the receiver. For example, the set command to change the recording
interval to 5 seconds is:
If a set command is accepted, an acknowledgment message is returned in the form:
If a set command is not accepted, an non-acknowledgment message is returned in the
form $PASHR,NAK*30. If a command is not accepted, check that the command has
been typed correctly, and that the number and format of the data parameters is correct.
Query Commands
The general structure of the query command is:
where str is a 3 character string identifier and x is the serial port where the response
message will be sent. The serial port field is optional. If the serial port is not included
in a query command, the response will be sent to the current port. For example, if the
user is communicating with the receiver on Port A and sends the following query
command:
The response will be sent to port A. However, if from the same port, the users sends
the query command:
Then the response will be sent to port B.
The format of the response message may either be in a comma deliminated format or
in a free form table format, depending upon the query command, Note that not every
set command has a corresponding query command. The most useful query command
to check the general status of most receiver parameters use:
